    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

There's potential in the A=[...new Array(w=1920).keys()];A.forEach(...) method.

It takes less characters to do a backwards for loop. for(i=w=c.width|=0;i--;)code

Charging animation speed is now constant… and program is 5 chars shorter.

Laptop only?
u/dwardu

Works on mobile/laptop, but on desktop appears as “100% & charging.” I would have liked to tackle this by modifying the expression to “ℓ<1&&b.charging?t%ℓ:ℓ”, but I couldn’t find a way to reduce a further 5 characters!
u/dwardu

Could be written as “ℓ<1&”, so 4 characters really.
u/AnnanFay

Hmm, on desktop-windows-firefox I'm just getting "navigator.getBattery is not a function"
u/AnnanFay

Ah, this would explain it: "From Firefox 52 onwards, the Battery Status API is only available in chrome/privileged code."
u/dwardu

Yes, after your comment I did some research and made this discovery too.

Why the square?
u/dwardu

It’s a real-time plot of Frames-Per-Second vs time; if it’s looking like a rectangle/square, it’s because your FPS is constant.
